2T0 aZZ ulhom it may concern.-

Be it known that I, WILLIAM BARKLA, a

I citizen of the UnitediStates, residing at Spokane, in the county ofSpokane and State of Washington, have invented certain new and usefulImprovements in Saw Swages and 'Shapers and Ido hereby declare thefollowing to be a full, clear, and exact description of the invention,'such as will enable others skilled in the art to which it appertains tomake and use the same. 1

My invention relates to saw swaging "and sharpening appliances; and itconsists of certainnovel features of combination and construction ofparts, the preferred form whereof will be hereinafter clearly set forth,and

pointed out in the claims.

The prime object of my invention, among others, is to provide a simple,though reliablyeflicient appliance of the characterspecified, wherebythe point of'atooth of a saw may be expeditiously shaped or fashionedand set in such a way as to produce the best imparted to the saw.

possible re sults when the saw is used.

Afurther'object of my invention is to provide means for shaping orupsetting the end of a saw tooth whereby a lateral extension on one sideof the tooth will be provided, thus makingit possible to direct eachalternate tooth to the left and the remaining teeth to the right so thatthe desired set will be Other objects and advantages hereinafter madeclearly apparent, reference being had to the accompanying drawings,which I are made a part of application, and in tion complete ready foruse. 4

which m Figure 1 shows an end view of my inven- Fig. 2 is a sectionalview as taken on line 2 2 of Fig. 3.= Fig. 3 is aside elevation of myinvention complete. Fig. 4 is a sectional view taken on line 4 4 of Fig.2. Fig.5 is a sectional view as taken on line 5 5 of Fig. 1. Fig. 6 is asectional view on line 6 o of Fig. 4. Fig. 7 is a detail in perspectiveshowing the toothclamping members located on either side of thesaw-tooth and also showing the shaper for the concave side of the tooth.Fig. 8 is a similar view to that presented inFig. 7, show- 7 ing oneside'of the tooth acted upon. Fig. 9 is a perspective view showing thetooth-en- "gaging member which cooperates with one taken on line 10 10of Fig. 3.

For convenience of description the various parts of my invention andcooperating accessories will be designated by numerals, the

same numeral applying to a similar part throughout the several views,and, referring to the numerals on the drawings, 1 indicates side of thetooth. Fig. 10 is a sectionalview l the body portion of my invention'orframework thereof, which is provided upon its under side, as will beobserved by reference to opening or recessdesignated by the numeral 3 ofproper size to receive the teeth-engaging members 4 and 5, one of whichis shown in de-' tail in Fig. 9 and consists of a suitable piece ofsheet steel, preferably roughened or scored upon its inner side, asdesignated by the numeral 6, whereby it will more reliably frictionallyengage a contiguous part of the saw. The tooth-engaging members 4 and 5are provided with beveled corners, as designated by the numeral 7, saidbeveled corners being coincident with the lateral spread or reach whichit is desired to impart to the sides of the saw-tooth, thus giving itthe requisite set or extension which will insure that the saw will passfreely through the log without undue friction or with such a sufficiencyof clearness i as will insure the best results.

It is obvious, therefore, that the extent of the bevel given to thecorner of the member 5 may be varied,

signed to be properly clamped within-the opening 3, provided in the bodyportion or framework 1, and this I am enabled to accomplish, as will beseen by referen'ce to Fig.

as desired. The members4 and 5 are de- 2, by means of the clampingmembers 8, said parts 4 and 5 being secured to said members in anypreferred way, as by the set-screws 9 or equivalent means, the headsofsaid setscrews being left flush-with the inner face or sideof saidmembers 4 and 5.

It will be observed by reference to Fig. 2 that the lower ends of themembers 4 and 5 are secured to the clamping members 8 by the'set-screws10, and in order that the said while their threaded ends are entered inthe able apertures in the body portion 1.

threaded seats 14, formed in the lower side of the framework or body 1.I have also provided a jam-nut 15 to hold the locking-bolts 13 in anadjusted position and have also formed upon said bolts a collar orauxiliary j am-nut 16, so that by turning said bolts 13 said members 8may be raised or lowered, as desired.

In order that the upper ends of the members 4 and 5 may be forcedtightly against the sides of the tooth of the saw-blade, which latter isdesignated by the numeral 17, I have provided the locking-bolts 18,seated in suit- One of the controlling-bolts 18 is provided upon itsouter end with the controlling-lever 19, having a suitable handle 20,while the other is provided with an angular head 21 for the control of awrench. Each of the bolts 18 is formed with a disk-like head 22, adaptedto fit in a slot 23, formed in the upper part of the members 8, as willbe clearly seen by reference'to Figs. 2, 4, and 5 of the drawings. Itwill be further observed that a recess 24 is formed near the ends of themembers 4 and 5 and also in a contiguous part of the members 8, saidcurved recess corresponding to the recess 25 in the inner edge of thesaw-tooth 26,

and designed to rest in said curved recess in all of said parts is theshaping-rod 27, which is eccentric in cross-section and is provided uponone end with the controlling-lever 28, having the hand-hold or member29, whereby the said shaping-rod 27 may be easily turned to act upon thepoint of the tooth in a manner hereinafter set forth.

By reference to Fig. 4 it will be further observed thata shaping-anvil30, designed to act upon the top or outer edge of the tooth is locatedin the anvil-seat 31, said anvil having a threaded extension or stem 32disposed in a threaded seat in a contiguous part of the casing 1, theouter end of the threaded stem having an angular head 33 for wrenchcontrol. The anvil is held locked in an adjusted position by the am-nut34, as clearly shown by reference to Fig. 4. A cam 30 is arranged underthe anvil 30 and one end thereof projects from the casing 1 and isprovided with a head 30 whereby it may be readily rotated by means of asuitable wrench. This cam 30 serves to support the anvil and preventinjury to its stem 32 when downward pressure is exerted thereupon. As aguide or index for the proper adjustment of my toothshaping instrument Ihave provided the member or cross-head 35, secured to the standard 36,the lower end 37 of which is designed to rest against the side of thesaw, while the upper end is formed with a slot 38, designed to receivethe clamping-bolt 39, earried by the arm 40, the latter being secured tothe framework or body portion 1 in any preferred way.

It will be seen that the member 36 is arranged in pairs, whereby thelower extension 37 will be disposed so as to rest upon either side ofthe saw, and thus prevent the member 35 from casually slipping off ofthe teeth. After the controlling-levers 19 and 28 are properly adjustedthey are respectively held against reverse movement by the crank-arms 41and 42, said crank-arms being locked in position by suitable set-screws43, it being understood that the inner ends of the crank arms or shafts41 and 42 are loosely seated in suitable apertures in the framework 1.

In using my invention the saw is entered in. the slot 2, so as to bringthe concave seat 25 in the saw-tooth in engagement with the side of theshaping-rod 27 and with the members 4 and 5 resting upon either side ofthe sawtooth. The shaping-anvil 36 is then forced inward against theouter edge of the sawtooth by placing a wrench upon the angular head 33,and after proper pressure has been brought to bear upon the point of thetooth the shaping-rod is turned through the mediation of thecontrolling-lever 28, with. the result that the tooth is spreadlaterally into the space provided by the beveled corners 7, thus leavingboth sides of the tooth so as to extend laterally and, in effect, insurethat the path cut by the teeth will leave a free clearance on both sidesof the body portion of the saw ind enable it to pass freely through thetim- While I have described the preferred combination and constructionof parts deemed necessary in materializing my invention, I desire tocomprehend in this application all substantial equivalents andsubstitutes.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a device of the character described, the combination with the bodythereof having a saw-receiving opening therein; of oppositely-disposedtooth-shaping members within the body, adjusting-screws mounted withinthe body and engaging and connected to the tooth-shaping members, andscrewthreaded supports depending from the body, said shaping membersbeing connected thereto so as to slide laterally and supported there- 2.In a device of the character described, the combination with a bodyhaving a sawreceivmg op emng therein of cl ampmg members within the bodyand at opposite sides of the opening, slotted ears extending iromsaidmembers, adjusting devices secured to the body and engaging andsupporting the ears, 5 said ears being mounted upon the adjustingdevices so as to slide laterally, means for independently adjusting theclamping members laterally, said members remaining parallel during theiradjustment, and tooth-shaping members adjustably secured to the 10clamping members.

In testimony whereof I have signed my name to this specification in thepresence of tWo subscribing Witnesses. v
